Product Description:

The RD52.3-8C-160-W-MV-FW is a high-power drive unit manufactured by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. Designed for panel installation in automated production lines, the unit converts DC bus energy into regulated three-phase output that commands industrial motors with adjustable speed and torque. By integrating into a closed-loop motion platform, it supports precise material handling, extrusion, and similar processes that require consistent motor performance under variable loads.

At its core, the controller uses Field oriented vector control, a modulation method that maintains real-time alignment between stator currents and rotor flux to enhance dynamic torque response. Thermal management is performed through Liquid cooling; coolant passages in the heatsink carry fluid so that fan noise and enclosure heat rise are minimized. The hardware belongs to generation 3, meaning it shares interface layouts and diagnostic functions with the latest RD52 modules. Power handling capability reaches 160 kW, allowing it to run large pumps or extruders from a single frame size. The DC link connection is specified as Inverter DC and the permitted bus voltage window tops out at 700 V, parameters that dictate compatible supply sections and protective devices. Firmware is not preloaded; it must be ordered as a separate subposition to match the desired application profile.

In operation the unit is delivered as an SFT inverter, so both the product variant and the internal configuration follow the same topology used in soft-torque tasks. When configured for Operating as RD51 SFT, it inherits command syntax from the smaller RD51 family, simplifying parameter transfer for multi-drive installations. Classified by the manufacturer as a Drive Controller, it integrates speed, current, and fault supervision into one enclosure, leaving only the motor feedback and cooling circuit to be supplied externally.
